VR-9SE

Our flagship VR-11SE is a large speaker by
anyone’s standards, being over seven feet tall and
weighing about 900 pounds per side. Using four
1,000-watt subwoofer amplifiers and 24 drivers per
system, it is easy to see why many audio critics
have called the VR-11SE “the best speaker in the
world”, with a bandwidth of 10 Hz to 100 kHz,
incredibly low distortion, and 99dB sensitivity.
Many of our customers wanted this type of sound in
their studios and living rooms, but needed a smaller
version that would accommodate space limitations
for both acoustics and aesthetics.

Our response was to develop the VR-9SE. The VR­9SE has the same bandwidth and transparency of
the larger sibling, but in a smaller and very
attractive package. How is this done? The solution
was simple. The VR-9SE represents exactly one
half of the VR-11SE. All of the components and
voicing is identical to that of the larger flagship, just
cut in half. While this smaller version does not
carry 99dB of sensitivity, it still holds its own as a
96dB loudspeaker, which by most standards
produces a very dynamic presentation in just about
any audio system.

A two-piece stacked and time-aligned design, each
VR-9SE consists of a 1,000-watt powered 15”
sealed subwoofer, twin 9” magnesium-coned mid­bass drivers, a 7” Aerogel midrange, a 1.5” dual
concentric ring Revelator tweeter, and a 5”
aluminum pure ribbon super tweeter. When
combined with Low Distortion Motor assemblies
and the highest quality crossover circuitry available,
this transducer array produces the finest and most
lifelike musical presentation available. Indeed, the
VR-9SE represents true sonic nirvana for those who
desire the very best.

If these qualities are your personal “Holy Grail” and
music is an important part of your life, the VR-9
Special Edition is for you! Our award-winning
technology has been praised by many esteemed
reviewers such as Robert Harley of Stereophile,
Harry Pearson of the Absolute Sound, Greg Weaver
and Clement Perry of Stereo Times, Rick Becker of
Enjoy the Music, and Paul Bolin and John Atkinson
of Stereophile. Famous clients include Alan
Menken, winner of seven Academy Awards for film
scores; Herb Alpert of A&M Records; MTV
Studios; Mobile Fidelity Sound Labs; JVC of
America, Hollywood video screening room;
Sheffield Sound Labs; Stan Ricker Mastering; Chris
Huston, recording engineer for Led Zeppelin, The
Who, Young Rascals, Pattie La Belle, etc; Blueport
Records and more than 40 professional recording
studios around the world.

The VR-9SE utilizes our proprietary Acoustic
Inverse Replication (A.I.R.) technology, developed
by Albert Von Schweikert while at California
Institute of Technology. A.I.R. employs our famous
Global Axis Integration Network to enable our VR­9SE to replicate the inverse of the recording
microphone signal, thus decoding the
dimensionality of the actual recorded event. In
combination with our rear-firing Ambience
Retrieval System, the VR-9SE will provide thrilling
realism, so close to a live performance, that you
will continue to ask yourself: “Is it Live or is it VR-
9?”

Specifications

System Type: Dynamic-driver six-way system
using acoustic suspension and a two-piece stacked
enclosure system; adaptive room correction
supplied for accurate sound in any environment.

Woofer Tuning: Acoustic suspension design
yielding the tightest mid-bass and sub-bass
reproduction possible, without the added problem
of “one note bass”, often associated with vented
designs. Large subwoofer cabinet design enables
accurate sub-bass reproduction down to 13Hz. On­board high power amplification allows for
incredible dynamic range, as well as custom­tailoring adjustments for varying room conditions.

Cabinet and Bracing: A two-inch thick front
baffle, sidewalls, and rear baffle provides
exceptional vibration control and image solidity,
while one-inch HDF interlocking braces provide
exceptional rigidity and freedom from boxy
colorations. The internal damping consists of thick
acoustic felt lining, foam, and Dacron stuffing to
eliminate cavity resonances. Large locking casters
are provided for ease of movement.

Size: Height: 50”, Width Front: 11”, Width Rear:
18”, Depth: 30”.

Weight: Woofer module: 255 lbs each,
M/T module: 95 lbs., System: 350 lbs. each tower.

Driver Complement (per side): (1)-15" Kevlar­Nomex honeycomb subwoofer, (2)-8.5” magnesium
mid-basses, (1)-7” carbon Kevlar-cellulose Aerogel
midrange driver, (1)-1.5” silk dual-concentric ring
Revelator tweeter, (1)-5” aluminum ribbon super
tweeter. All drivers use a proprietary Low
Distortion Motor system.

Crossover: Hovland film and foil capacitors, Solen
film-foil capacitors, Solen Perfect Lay air-core
inductors, military-spec film-foil resistors.
Crossover points and architecture are classified.

Binding Posts: Two sets of five-way WBT
platinum posts enabling bi-wiring. Single wire can
be used direct to M/T with jumpers to the woofer
cabinet.

Ambience Driver: Rear-firing 5” aluminum pure
ribbon. Ambience circuit uses Dimensional Control
to compensate for room acoustics and soundstage
depth, providing a Global Axis polar response
pattern to simulate live musical reproduction.

Fine Tuning Adjustments: Subwoofer level
control and frequency tuning variable from 50Hz to
100Hz. Front tweeter level control adjustment
centered at 4 kHz with 3dB gain and 18dB cut.
Front super tweeter level control adjustment
centered at 20 kHz with 10dB gain and 11dB cut.

Subwoofer Amplifier Power: 1000 watts rms
Class D technology (one for each subwoofer).
System total is 2000 watts rms, 4,000 watts peak.

Frequency Response: 15-35 kHz, +/- 2 dB, 13 Hz­100 kHz –6 dB, (+/- 1dB at mid band).

Impedance: 6 ohms avg. (8ohm M/T; 4ohm
Woofer).

Recommended Power: 20 watts up to 1000 watts
Sensitivity: 94 dB @ 1w/1m using 2.83 V. (96 dB

with subwoofer and super tweeter boost settings).
Warranty: Twenty years Parts and Labor,

excluding burned voice coils due to amp clipping.
Amplifiers are warranted for three years. Warranty
